一、阶段性总结

创新实训已经去了四周，目前正在进行前端管理员系统功能的实现，不过还是要现总结一下上一阶段的工作成果：

（1）自学了TP5.0，JQuery, Bootstrap 等框架

（2）完成了后台数据库的搭建

（3）基本实现了注册登陆界面的全部功能

二、具体工作内容

1.数据库搭建

数据库的设计和代码由其他组员实现：见https://blog.csdn.net/where_is_horse/article/details/79849209

数据库 shixun:


teacher:


manager:


2.前端登陆界面功能实现

view:


功能实现：

（1)验证码的实现（验证码的实现会单独发文章说明）

使用了TP5.0提供的think-captcha包，之后会详细说明。


（2）TP5.0下实现登陆验证

账号：[email protected](id:1 phone:17864151234)

密码：123456

用户名错误：（优先判断用户名，密码验证码不考虑）


密码错误：


验证码错误：


登陆成功：


（3）选择登陆方式：

管理员身份登陆：（刚才的用户账号提示不存在）


代码实现：


在Login控制器下写check（）方法实现登陆验证，通过对单选框进行一个简单的判断来实现不同身份的登陆验证。

（4）防止用户未登录就进入系统界面


利用session，在用户试图访问用户系统界面时，判断用户当前是否为登陆状态，否，则阻止本次访问，跳转页面到登陆页面，时，则允许用户访问。

3.注册页面的实现


（1）注册验证：Validate

通过下载并导入JQuery.Validate包实现了基于js的注册验证功能



（2）注册判定





成功注册：

四、感悟与收获

    到目前为止，我真的学到了很多很多以前根本不会去接触的东西，像底层的html,css,js,php,以及对应的框架bootstrap,jquery,tp5.0 ，这些语言与框架的存在让我不再惧怕前端网站成千上万条代码，毕竟语法在那摆着，不存在看不懂的东西，在今后的学习生活中，我还会进一步学习这些工具，争取精通这些前端语言，成为一个web工程师！！
